2. Introduction – Home temperature context An idea from ubiquitous computing: collect data from sensors to make inference about user current context. Then to make decision that make user feel comfortable. Using temperature sensor and current out-door temperature we may know if the temperature context of a house is comfortable or not. Some third parties may be interested in this context and are eager to help.

5. Scenarios Overtime, raw data from sensor is send to InputProcessor component. MsgID = 30 Input processor component extract temperature data, send Temperature Reading message to SIS. MsgID = 101. SIS relays to HomeContextMonitor component. Overtime, OutdoorTemperature component extract outdoor temperature data in the areas where client lives, feed to the HomeContextMonitor. MsgID = 102. HomeContextMonitor based on room temperature and outdoor temperature, send alert message to SIS if the values excess some thresholds. MsdID = 38. (table in slide #3). SIS relays the message to uploader. Uploader receive message ID = 38, upload to the website. The website displays the content based on who is the client. For example, only fire department can see the alert that room temperature is too hot, while the vendors and department manager can see data if the temperate is in the “not so comfortable” threshold.
